Climate Change Timeline - an unexpected proponent of a new ice age...

In the August 2009 Number of the month, you will recall our bending author linked us to a Climate Change Timeline....http://butnowyouknow.wordpress.com/those-who-fail-to-learn-from-history/climate-change-timeline/

I was interested to find this litle tit-bit when internet searching "Global Chilling":
http://dangoldfinch.wordpress.com/2007/09/22/global-chilling-what-is-this/

It appears to credit James Hansen with a 1971 prediction we were entering a new ice age with a 6degC temperature drop....

I must do some more searching on this but if anyone has any information, please add it here.

I did find this reference through Google SCholar search:
http://www.sciencemag.org/cgi/content/abstract/sci;173/3992/138
which provides an abstract which says...among other things, "the rate of temperature increase diminishes with increasing carbon dioxide in the atmosphere" but does lead on to the Ice Age concern.
But, unless I buy a subscription, I am having a hard time verifying any link with Hansen.

In this article (http://www.washingtontimes.com/news/2007/sep/19/inside-the-beltway-69748548/) it says:
"The article goes on to say that Mr. Rasool came to his chilling conclusions by resorting in part to a new computer program developed by Mr. Hansen that studied clouds above Venus.

The 1971 article, discovered this week by Washington resident John Lockwood while he was conducting related research at the Library of Congress, says that "in the next 50 years" — or by 2021 — fossil-fuel dust injected by man into the atmosphere "could screen out so much sunlight that the average temperature could drop by six degrees," resulting in a buildup of "new glaciers that could eventually cover huge areas."

Oops! a computer program? Why am I not surprised?

Hanson denies he believed in an Ice Age here:

Of course, the time to have made these comments was in 1971 when the S I Rasool paper was published.....not wait till the 21st century....

I won't go broadcasting copyrighted material here, but go find a student with a half decent university and she'll have full text access through her library. In Rasool 1971 the only cited article with Hansen among the authors is:

J. E. Hansen and J. B. Pollack,
J. Atmos. Sci. 27, 265 (1970).

and deals with the measurement of cloud properties.
